English - Safe Host

isks, as is the case here outside the city center, our security concept also includes the use of bestof-breedsafety and security technology from Siemens. In addition, our entire data center isdesigned for high redundancy according to the N+1 principle: This extends not only to IT, but alsoto essential systems such as uninterruptible power supply (UPS), emergency generators and theautomatic extinguishing system.”State-of-the-art extinguishing solutions for data centersSafe Host owns a six-story building, five of which are occupied almost entirely by IT equipment.The top floor is used by company management and administration. The expansion of the five-storydata center was driven by demand: Step by step, one floor after the other, from the top of thebuilding towards the bottom, was equipped with the necessary technology. For this reason, SafeHost’s building now contains different generations of fire detectors, fire control panels andextinguishing control panels from Siemens—some floors still use fire detectors and control panelsfrom the older AlgoRex line, while most are equipped with devices from the current Sinteso family.All fire safety and security devices are managed using a Siemens LMS 6 central managementstation. The LMS 6 collects information from more than 2,800 data points and visualizes them on60 graphical displays of all the floors, offering varying levels of detail.Today, Safe Host’s building is divided into 350 fire detection zones. No fewer than 830 highlysensitive fire detectors from the Sinteso and AlgoRex families are in use. To ensure reliable firedetection, they are supported by approximately 30 aspirating smoke detectors which continuouslyanalyze the room air for smoke particles. In addition, some 50 manual call points are installed atstrategic locations throughout the building. All detectors are connected to a total of four AlgoRexCC11 fire control panels, supplemented by four AlgoRex floor repeater displays. In an emergency,65 alarm sounders make sure that the building is evacuated quickly.The automatic extinguishing system meets all the requirements specific to data centers. Water orwater mist cannot be used to extinguish a fire in a data center: The moisture would potentiallycause more damage to the sensitive electronics of the servers and storage devices than the fireitself. For this reason, Safe Host uses a Sinorix N 2 gas extinguishing system. If the fire detectorsdetect and confirm a fire, the system automatically triggers the extinguishing process. Valves onthe gas tanks in the basement of the building are opened and nitrogen, an inert natural gas, flowsthrough a complex piping network into the room where it is needed. There nitrogen displacesoxygen, robbing the fire of one of its essential components. All of this happens in a matter ofminutes and it is an effective way to extinguish both open fires and smoldering fires.
